Krokta Rum is Jesper Canell and Viktor Ottosson, who are based in Sweden and specialize in experimental sound art. Two 20-minute long sides in the second volume in this “Tankar & Syner” series, where Krokta Rum explores worlds beyond the physical realm. These are wonderful experimental, drone and industrial noises along with field recordings of what sounds like some kind of destruction taking place, but who knows? It is really hard to tell what is actually going on and where those noises are coming from.
